Abstract: ABSTRACT                                   3-14558/+   Impregnation of Reinforcement With Epoxide-Photopolymeri-zable Compound Composition to Prepare Prepregs Prepregs which are tacky to dry to the touch can be prepared by impregnating a solid reinforcing material with a liquid, solvent-free composition containing a) an epoxide resin, b) a photopolymerisable compound, c) a heat-activa-table curing agent for the epoxide resin a) and, if approp-riate, a photopolymerisation catalyst for the photopolymeri-sable compound b), and the composition is exposed to actinic radiation.  The composition solidifies thereby to give an essen-tially solid layer as the result of photopolymerisation of the photopolymerisable compound, whereas the epoxide resin remains substantially in a heat-curable state.  In accordance with the invention, a substituted or unsubstituted aliphatic, cycloaliphatic or araliphatic amine is used as the heat-activatable curing agent c), and the photopolymerisable com-pound b) is employed in such a ratio to the heat-curable com-ponent a) that, after irradiation with actinic light, the composition can still be shaped by thermoplastic methods. The prepregs thus obtained are suitable for the production of reinforced composite materials, such as skis, tennis rackets or car body components by hot-curing.

The rupture disc includes a thickness reducing groove at least partially circumferentially surrounding the dome portion and located in the transition region thereof.  Preferably, the rupture disc is of the reverse buckling type and the groove does not completely surround the dome portion so as to define a tab or hinge within that part of the transition region which is ungrooved or not as deeply grooved as a remainder of the transition region.  In addition, the slope or radius of curvature may be increased in the region of the tab.  The rupture disc also includes an indentation on the dome portion.  The indentation is preferably greatest on the dome portion at a location spaced from the transition region and directly between the tab and a crown of the dome portion.  In addition, the mounting mechanism includes a lower ring member having an arcuate projection which extends into the vent.  Preferably, the arcuate projection is located so as to be relatively close to and so as to align with the tab such that the dome portion wraps about the projection when reverse buckling and rupture occurs.  Methods are disclosed for producing the disc with the groove and the indentation.

Title: Process for the production of cast iron with  vermicular graphite
Inventor: MENK WERNER
IPC: C22C33/10
Filed: 1985-03-21
Granted: 1989-02-28
Abstract: Abstract There is disclosed a process for the production of cast iron with an intermediate structure of vermicular graphite, in which a GGG melt (for making cast iron with spherulitic graphite) is used as a starting melt, and such starting melt can be produced in a converter in an accurate and reproducible way, whereby there are constant sulphur and oxygen amounts.  Proceeding from this data regarding the GGG melt, sulphur is additionally mixed with the melt and the amount added is determined in accordance with the formula:       S = A . Mg - B, wherein, S = added amount of sulphur-containing material based on pure sulphur in % by weight, Mg = magnesium content of the starting melt in % by weight, A = magnesium factor: 0.9 ? A ? 1.2, B = sulphur constant: - 0.02 ? B ? + 0 05.       The addition of sulphur to the starting melt is such as to increase the magnesium/sulphur ratio present in the starting melt so as to lie in the range 2:1 to 1:1, whereby the spherulitic graphite is converted into vermicular form.       The accuracy and reproducibility of the proposed method is due mainly to the fact that in the first step of the process (production of the GGG starting melt), instablility factors are already eliminated by virtue of the known Georg Fischer production technique for making GGG.  In addition, it is the only process known until now which is suitable for use in an automatic installation for the optional casting of GGG or GGV.

Abstract: Abstract of the Disclosure A filter unit for making coffee, tea or other beverages consists of a filter pouch and a rod for suspending the pouch in a cup or similar container.  The pouch has a water permeable bag portion in which ground coffee, tea or other beverage flavoring can be placed, and a mouth portion into which liquid can be poured to filter through the flavoring and through the permeable bag portion into the cup.  The mouth portion is stiffer than the bag portion, being reinforced by folding the water permeable material of the pouch onto itself, and holes are pierced through the mouth portion to receive the rod.  The rod passes through the holes midway between side edges of the pouch.  The holes are slightly larger than the rod and the rod is smooth, and a pouch containing coffee or the like tends to open if the rod is jiggled.  The side edges of the pouch diverge upwardly and can engage opposite sides of the cup to press the mouth portion to an open position as the pouch is lowered into the cup.  The rod has a pair of smooth knobs which receive the rim of the cup between them to locate the rod transversely of the rim so that the rod supports the pouch in the cup.  The pouch is easily dropped off the rod when the filter unit is removed from the cup.

Abstract: INSULATING MATERIAL AND USE THEREOF IN INSULATORS                         ABSTRACT   An improved insulating material is provided. The insulating material is a mixture of an insulating fluid and solid insulative bodies. The insulating material exhibits desirable insulating, conformal coating, surface adhesion, and low-viscosity characteristics. For example, when the insulating material is used to fill the cavity of a hollow insulator, the insulating material prevents any moisture that enters the insulator from adhering to the walls that define the cavity; thus maintaining the insulating qualities of the insulator. In the event that some of the fluid is lost through leakage, the insulating material also aids in preserving the insulating qualities of the insulator.

Abstract: Abstract:   The apparatus provides a method of observing a water sample that is caused to flow rapidly past a beam of light of rectangular cross section.  Attenuation of the beam by the sample is measured in a first detector that generates an output signal that has a basic, relatively slowly changing (e.g. half a second) component representative of the overall turbidity of the sample, and a series of short (e.g. 6 millisecond) pulses caused by individual, larger particles in the sample.  The basic component is fed to a feedback circuit which so controls the light source as to maintain such component substantially constant.  The intensity of the light source then provides a measure of the turbidity.  A second detector counts the number of pulses above a certain threshold magnitude.  In addition, this second detector can momentarily (during the occurrence of such a pulse) open a switch to prevent the feedback circuit from receiving the output signal of the first detector and hence avoid its reacting to the pulse.          During this switched off time the output of the feedback circuit is held substantially constant by a capacitor.          In what is expected to be its most important application, the apparatus will be used with sea water samples to obtain simultaneous measurements of the concentration of phytoplankton (typically 1 to 10 µm in diameter), as reflected in the turbidity of the sample, and counts of zooplankton (typically 0.4 to 20 mm diameter) which can be individually detected as pulses and counted by the second detector.  However, the apparatus can also be used for measuring other  factors causing turbidity in water samples, e.g. the presence,  of small non-organic particles, while simultaneously counting larger particles, which can include small fish as well as zooplankton.
